Method for plating boron carbide on diamond surface
The invention discloses a method for plating boron carbide on a diamond surface. The method comprises the following steps: boriding on the diamond particle surface under the conditions that the vacuum degree is less than 100 Pascal, the temperature is preserved to 300 DEG C for 30 minutes and the temperature is preserved to 1200 DEG C for 3-12 hours, thereby plating a boron carbide film on the diamond surface. According to the diamond of which the surface is plated with the boron carbide film prepared by the invention, the binding force between a metal matrix and the diamond can be improved, the erosion resistance of the diamond to oxygen, iron, nickel and cobalt can be greatly improved, and the phenomena such as oxidation and graphitization of the diamond in the process of preparing a diamond-impregnated drill bit can be effectively avoided, so that the diamond inlaid into the metal matrix is complete in appearance, clear in edges and stable in performance. Therefore, the abrasive ratio of the manufactured appliances is greatly improved, and the service life is obviously prolonged.
